Definitions

  • the present invention relates to a method for charging accumulators, especially for gel, fleece and wet accumulators, using a controllable current and voltage source and a control device, with a Main and reload phase, the charging current being constant in the main charging phase is held until the charging voltage reaches a predefinable voltage limit.
  • Charging methods are known in which a temperature rise in the Accumulator together with a voltage or current measurement as Controlled variable is used.
  • Charging voltage or the charging current to be measured with difference values compare and when reaching predetermined differences and when reaching predefined difference values to use these for regulation.
  • Such a charging method is, for example, from US 5,589,755 known, the voltage after switching off the charging current again and again a predetermined no-load voltage is compared.
  • the invention is based on the object of improving a charging method of the type mentioned at the outset, avoiding the disadvantages described, in such a way that a less complex and more reliable charging of batteries is independent of the various types of batteries, their respective charging temperature, their degree of aging and the like is made possible.
  • the method of the type mentioned is improved in such a way that the change in the charging current over time is then determined at a constant charging voltage and, when a predeterminable change in the charging current over time is reached, the charging current flowing at that time is kept constant and in In the recharging phase with this charging current, the change in the charging voltage over time is then determined and the charging process is ended when a predefinable change in the charging voltage over time is reached.
  • the main charging phase a safe termination of the main charge by reaching the predeterminable Charging current determined over time.
  • the time for the start of the reload phase is set within which then changes the charging voltage at this constant charging current determined reliably over time and when a predeterminable level is reached Change value of the charging voltage over the time of the charging process safely is ended.
  • the for Reload phase required depending on the Accumulator type determined, with the increase in the after the main charging phase Charging voltage determined over time and the charging current based on this value is specified for the reload phase.
  • the for Reload phase required current depending on the type of accumulator determined, after the main charging phase, the charging current I switched off Decrease in the charging voltage is determined and the charging current for the reload phase is specified and switched on.
  • the for Reload phase required charging current depending on the type of accumulator determined and turned on, especially with regard to the used Electrolytes in gel, fleece and wet accumulators are important because they need different sized charging currents to ensure a full charge.
  • the Charging ends during the main charging phase if a predetermined one maximum main charging time is exceeded.
  • the Charging also ends during the main charging phase if one predetermined maximum constant current phase of the charging current is exceeded.
  • the charging process is ended during the reload phase, if a predetermined reload time is exceeded.
  • the charging current I is kept constant at a predeterminable charging current I 1 .
  • the charging voltage U rises slowly within this time t ic .
  • the charging voltage U is kept constant at this value U 1 and the charging current I is switched off.
  • Sections 1 and 2 can be seen. This section is identified in Figures 1 and 2 with t uc , the time of the maximum constant voltage phase . Sections 1 and 2 thus determine how the FIGS. 1 and 2, the maximum main charging time T hl ; which is composed of the time of the maximum constant current phase t ic and the time of the maximum constant voltage phase t uc .
  • the change in the charging voltage U over time is then determined at this charging current l 2 and the charging process is ended over time when a predefinable change value du / dt in the charging voltage U is reached.
  • the charging current l 2 for the recharging phase is determined in a determination phase following the main charging phase.
  • the determination phase can take place according to two different methods, which are shown in FIGS. 1 and 2.
  • the recharge current I 2 required for the recharge phase is determined as a function of the type of accumulator, ie with regard to a wet, fleece or gel accumulator, with the increase du / dt of the charge voltage U over time after the main charge phase is determined and the charging current l 2 for the recharging phase is specified on the basis of this value, as shown in FIG. 1 in the section labeled 4.
  • the required recharging current l 2 is specified for a wet, fleece or gel accumulator.
  • the current and voltage values required for this are stored changeably in the control device.
  • the accumulator is then charged further with this charging current l 2 and finally the change in the charging voltage U over time is determined within the recharging phase and when the predetermined change value du after the charging voltage U over the time the charging process is ended, as in FIG. 1 in the sections marked 5 and 6.
  • the charging current l is switched off after the main charging phase has ended and the drop du / dt of the charging voltage U over time is determined, as shown in FIG Section shown.
  • the charging current I 2 required for the recharging phase for wet, fleece or gel accumulators is specified and switched on.
  • this charging current l 2 as shown in the sections marked 5 and 6 in FIG. 2, the change in the charging voltage U over time is determined and the charging process is ended over time when a predeterminable change value du / dt of the charging voltage U is reached .
  • the block diagram shown in FIG. 3 shows the sequence during the main charging phase, corresponding to the one in FIGS. 1 and 2 sections marked with 1 and 2.
  • the charging current l is set to this current value l 2 for the recharging phase.
  • the main charging phase is now complete.
  • the block diagram shown in FIG. 4 shows the course of the recharging phase, the change in the charging voltage U over time then being determined in the case of the charging current l 2 when the charging process U over the time has ended when a predeterminable change value du / dt is reached.
  • the charging voltage U is compared with a predeterminable maximum voltage for the recharging U 2 .
  • the area framed in FIG. 4 shows how the change in the charging voltage U is determined over time.
  • the respective voltage value of the charging voltage in the last loop pass U load is subtracted from the charging voltage U and compared with a predetermined limit value of the voltage change U g , as shown in FIGS. 1 and 2 in sections 5.
  • the in Figs. 3 and 4 flowcharts further include safety shutdown mechanisms that terminate the loading process.
  • the main charging phase shown in FIG. 3 is ended when a predetermined maximum main charging time t HL or a predetermined maximum constant current phase t ic of the charging current I is exceeded.
  • the charging process is ended within the reloading phase shown in FIG. 4 when a predetermined maximum reloading time t v is exceeded.
  • FIGS. 5 and 6 show two different determination phases for determining the recharging current l.
  • FIG. 6 shows in a block diagram the sequence of the determination of the charging current l 2 for the recharging phase according to FIG. 1.
  • the block diagram according to FIG. 6 is inserted at the points marked 1 and 2 on the block diagrams according to FIGS. 3 and 4.
  • the increase du / dt of the charging voltage U over time is determined after the main charging phase in accordance with FIG. 3, and the charging current l 2 for the recharging phase as a function of the respectively determined accumulator type, ie for Wet, fleece and gel accumulators specified.
  • the charging voltage U is compared with the voltage limit U x to identify the type of accumulator. This comparison is included in two different time comparisons, which can be used to determine what type of accumulator to be charged. On the basis of these comparisons, it is then determined with which charging current I 2 the recharging phase is carried out.
  • the respective values for the time comparison and the recharging current l 2 for wet, gel or fleece accumulators can be specified by the control device.
  • the waste du / dt of the charging voltage l determined over time and uses this value of the charging current I 2 for the Reload phase specified and switched on.
  • the voltage drop of the charging voltage U is also compared by a comparison with the voltage limit U x to identify the type of accumulator, this comparison also being included in two time comparisons.
  • the charging current l 2 for get, wet or fleece accumulators can also be specified by the control device. 6 is already like FIG. 5 in the course of the loading process between FIGS. 3 and 4 inserted at points 1 and 2.
